What do you mean by coercive force?
Definition of coercive force : the opposing magnetic intensity that must be applied to a magnetized material to remove the residual magnetism.
What is the importance of retentivity and coercivity for a magnetic materials?
Answer: Hysteresis loop provides a substance with the importance of retentivity and coercivity. Therefore the way to select the right material to make a permanent magnet is made simpler by the heart of machines.
What is coercive force in electrical?
Coercivity, also called the magnetic coercivity, coercive field or coercive force, is a measure of the ability of a ferromagnetic material to withstand an external magnetic field without becoming demagnetized.
What is coercive force in hysteresis?
Coercive Force – The amount of reverse magnetic field which must be applied to a magnetic material to make the magnetic flux return to zero. (The value of H at point C on the hysteresis curve.) Permeability, m – A property of a material that describes the ease with which a magnetic flux is established in the component.
What is coercive force in sociology?
Coercion is the use of force to achieve a desired end. It may be physical or non-violent. It is the ultimate means of social control when all other means fail. If a society has to depend on external force it shows its weakness rather than strength in social control. …
What is coercive force in law enforcement?
A police officer uses coercive force to get a person to obey an order or command. The fact that the officer has a gun and other weapons, as well as legal authority, can be used in a coercive manner, to make a person do what he or she is told.
What is hysteresis effect?
The magnetization of ferromagnetic substances due to a varying magnetic field lags behind the field. This effect is called hysteresis, and the term is used to describe any system in whose response depends not only on its current state, but also upon its past history.
What is hysteresis law?
When a ferromagnetic material is magnetized in one direction, it will not relax back to zero magnetization when the imposed magnetizing field is removed. The lack of retraceability of the magnetization curve is the property called hysteresis and it is related to the existence of magnetic domains in the material.
What are the consequences of using coercive power?
A manager uses coercive power by forcing employee compliance through use of threats. While coercion may work in the short-term, you do risk long-term problems, including low employee job satisfaction resulting in high employee turnover. Productivity may even decrease in the long-term.
Why do people use coercion?
The purpose of coercion is to substitute one’s aims to those of the victim. For this reason, many social philosophers have considered coercion as the polar opposite to freedom.
Is coercive power effective?
Coercive power is effective as long as there are sufficient resources to detect breaches of rules and to undertake subsequent punishment (Becker, 1968; Mulder et al., 2009).
Why do police use coercion?
Put simply, police coercion takes place when officers of the law exert undue pressure to get an individual suspect to admit their involvement in a crime. It is important to note that not all coerced admissions of guilt are false confessions.
What is coercive power and how does it work?
Coercive power is also effective when preventing harassment in the workplace. The threat of termination or a civil lawsuit as a punishment helps to reinforce harassment policies set in place by the organization. Coercive power gives a leader control over what is happening in their organization.
Why is coercive force important in a relay?
Coercive force is important as it indicates the amount of hysteresis which a material exhibits. In an electromechanical relay ( Figure 8.3) the magnetic circuit has quite a large air gap in it when the relay armature is in the relaxed ‘open’ state.
What is coercivity and coercive force?
Coercive Force is another way of saying Coercivity. The terms are used interchangeably. Coercivity is expressed in the SI system as A/m or kA/m. That is Amperes-per-meter or kilo-Amperes-per-meter.
What is coercive power of leadership?
Coercive power gives a leader control over what is happening in their organization. It maintains employee discipline, enforces organization policies, and maintains a harassment free environment. At times, punishment, or even the threat of punishment is necessary to establish a successful, incident free organization. References:
